Ants in my cherry tree?

[veritas629]

I put this cherry tree in my backyard last year. Got a small handful of cherries this year, but the damn birds got most. I'll do a better job of netting next year, live & learn. Had slugs too and I was looking to squash them yesterday when I found these. I think they are ant nests, but not sure. Anyone know what I got going on here? Is this harmless nature doing its thing or are they something I should remove?

Look more like mites with that tick shape. Purify it with chemical or flame.

They arent ants or mites but black root aphids.

Hit them with a pesticide, I'd use a systemic pesticide like imidacloprid which the plant will absorb and kill any insect for 60-90 days, safe to use on consumables but you dont want to treat it when it's fruiting

yeah i'd say black aphid
did you use anything like blood & bone or any high N nutrient

Well there ya go. When I saw that pic I thought fuck they look like aphids and had a PTSD experience haha worst pest EVER

Fruit is done for the year, so I bomb them with whatever our friendly garden centre guy suggests. His advice is always good. No blood & bone ferts, just basic compost and an occasional handful Charlie Carp pellets or Osmocte Citrus & Fruit, not often and not much.

Found some of this in the shed and dusted the entire tree. It mentions aphids and the ants will hate the dust too.

Aphid are generally attracted to plants that have had a higher nitrogen take up , the charlie carp would be high but generally not excessive i would think , the Osmocote Citrus & Fruit is probably high & it's slow release so every time you water or it rains the plant gets a hit of higher N , next year just try regular top dresses of compost &/or castings , keep it mulched & the moisture consistent & you should do well along with a regular IPM plan
